Parakeet Auklet
Parakeet Auklet, 23–25 cm, breeds on rocky islands and cliffs of the Bering Sea and North Pacific. Upturned bright orange-red bill, white facial plume. Unlike most auklets, feeds on jellyfish, medusae, and crustaceans rather than euphausiids. Winters far offshore in the North Pacific.
Atlantic Puffin
「海のピエロ」とも呼ばれるニシツノメドリは、北海の崖に穴を掘って営巣する魅力的な海鳥。口蓋に後ろ向きの棘があるため、一度に12匹もの魚を横向きにくわえて運ぶことができる。気候変動と乱獲による餌不足が脅威となり、個体数が減少している。
